Hiperglicemia y diabetes inducidas por esteroides / Hyperglycemia and steroid-induced diabetes

La hiperglicemia y/o diabetes inducida por esteroides, se define como la elevación de la glicemia, causada por la acción de los fármacos glucocorticoideos, sobre el metabolismo de los carbohidratos, y presenta una prevalencia entre un 20% al 50%, en pacientes sin diabetes previa, existiendo mayor riesgo para esta patología en pacientes con diabetes pre-existente, obesidad, uso crónico de esteroides o en dosis altas, entre otros. El diagnóstico se rige por los criterios para diabetes en la mayoría de los casos. No obstante, existen casos en donde la hiperglicemia por esteroides es sub-diagnosticada. Su manejo se basa en el tratamiento farmacológico (antidiabéticos orales, subcutáneos e insulina) y no farmacológico (dieta y ejercicio), tomando en cuenta, el patrón glicémico, peso, edad, co-morbilidades, dosis, tipo y tiempo de uso de los esteroides. La relevancia de conocer como diagnosticar y tratar dicha patología, se debe al riesgo de ingreso hospitalario, de infección, de mala cicatrización y de mortalidad en casos no tratados. En vista del aumento del uso de glucocorticoides en la actualidad, se hace una revisión del abordaje terapéutico de la hiperglicemia y diabetes inducida por esteroides.

Hyperglycemia and Steroid-induced Diabetes is defined as the elevation of glycemia caused by the action of glucocorticoid drugs on carbohydrate metabolism, with a prevalence between 20% and 50% in patients without Diabetes. Though, there is a greater risk of this pathology in patients with pre-existing Diabetes, Obesity, chronic use of steroids or in high doses, among others. In most cases, the diagnosis is governed by the criteria of Diabetes; however, there are cases where hyperglycemia Steroid-induced is under-diagnosed. Its management is based on pharmacological treatment (oral and subcutaneous hypoglycemic agents and insulin) and non-pharmacological treatment (diet and exercise), in accordance with the glycemic pattern, weight, age, co-morbidities, dose, type and the duration of the use of steroid. The relevance of knowing how to diagnose and treat this pathology is the risk of hospital admission, infection, poor healing and mortality in untreated cases. In view of the increased use of glucocorticoids nowadays, a review is made about the therapeutic approach to hyperglycemia and steroid-induced Diabetes.

ABSTRACT Objective: to identify evidence in the literature on the possible risk factors for the risk of unstable blood glucose diagnosis in individuals with type 2 diabetes mellitus, and to compare them with the risk factors described by NANDA International. Method: an integrative literature review guided by the question: what are the risk factors for unstable blood glucose level in people with type 2 diabetes mellitus? Primary studies were included whose outcomes were variations in glycemic levels, published in English, Portuguese or Spanish, in PubMed or CINAHL between 2010 and 2015. Results: altered levels of glycated hemoglobin, body mass index>31 kg/m2, previous history of hypoglycemia, cognitive deficit/dementia, autonomic cardiovascular neuropathy, comorbidities and weight loss corresponded to risk factors described in NANDA International. Other risk factors identified were: advanced age, black skin color, longer length of diabetes diagnosis, daytime sleepiness, macroalbuminuria, genetic polymorphisms, insulin therapy, use of oral antidiabetics, and use of metoclopramide, inadequate physical activity and low fasting glycemia. Conclusions: risk factors for the diagnosis, risk for unstable blood glucose level, for persons with type 2 diabetes mellitus were identified, and 42% of them corresponded to those of NANDA International. These findings may contribute to the practice of clinical nurses in preventing the deleterious effects of glycemic variation.

Utility of body mass index, waist circumference and waist-to-height ratio as screening tools for hyperglycemia in young people

ABSTRACT Objectives To evaluate the ability of BMI, WC and WHtR to discriminate hyperglycemia in young people, and to determine whether there is an increase in the accuracy with the addition of WC and/or WHtR to BMI. Subjects and methods A cross-sectional study was conducted on 1,139 schoolchildren aged 6 to 17 years from Northeastern Brazil. Body weight, height, WC and fasting glucose levels were measured, and the BMI and WHtR were calculated. The presence of hyperglycemia was defined as a fasting glucose level ≥ 100 mg/dL. Results The prevalence of hyperglycemia was 6.6%. Strong correlations were observed between the anthropometric indicators studied (BMI vs. WC = 0.87; BMI vs. WHtR = 0.87; WC vs. WHtR = 0.90). Hyperglycemia was more likely to be present in young people with excess weight (PR = 1.70), high WC (PR = 1.85), and high WHtR (PR = 1.91). The accuracies to discriminate hyperglycemia were significant, but low, for the individual (BMI = 0.56; WC = 0.53; WHtR = 0.55) and combined indicators (BMI + WC = 0.55; BMI + WHtR = 0.55). Conclusion Our findings do not support the use of BMI, WC or WHtR as screening tools for hyperglycemia in children and adolescents.

Hyperinsulinemia and hyperglycemia: risk factors for recurrence of benign paroxysmal positional vertigo / Hiperinsulinismo e hiperglicemia: fatores de risco para recorrência de vertigem postural paroxística benigna

INTRODUCTION: Changes in carbohydrate metabolism may lead to recurrence of benign paroxysmal positional vertigo.OBJECTIVE: To evaluate the influence of the disturbance of carbohydrate metabolism in the recurrence of idiopathic BPPV.METHODS: A longitudinal prospective study of a cohort, with 41 months follow-up. We analyzed the results of 72 glucose-insulin curves in patients with recurrence of BPPV. The curves were classified into intolerance, hyperinsulinemia, hyperglycemia and normal.RESULTS: The RR for hyperinsulinism was 4.66 and p = 0.0015. Existing hyperglycemia showed an RR = 2.47, with p = 0.0123. Glucose intolerance had a RR of 0.63, with p = 0.096. When the examination was within normal limits, the result was RR = 0.2225 and p = 0.030.DISCUSSION: Metabolic changes can cause dizziness and vertigo and are very common in people who have cochleovestibular disorders. However, few studies discuss the relationship between idiopathic BPPV and alterations in carbohydrate metabolism. In the present study, we found that both hyperglycemia and hyperinsulinemia are risk factors for the recurrence of BPPV, whereas a normal test was considered a protective factor; all these were statistically significant. Glucose intolerance that was already present was not statistically significant in the group evaluated.CONCLUSION: Hyperinsulinemia and hyperglycemia are risk factors for the recurrence of idiopathic BPPV and a normal exam is considered a protective factor.

INTRODUÇÃO: As alterações do metabolismo do carboidrato podem levar a recorrência de vertigem posicional paroxística benigna.OBJETIVO: Avaliar a influência dos distúrbios do carboidrato na recorrência da VPPB idiopática.MÉTODO: Estudo longitudinal, do tipo coorte, prospectivo, com 41 meses de acompanhamento. Analisaram-se 72 resultados de curvas glicoinsulinêmicas em pacientes portadores de recorrência de VPPB. As curvas foram classificadas em intolerância, hiperinsulinemia, hiperglicemia e normal.RESULTADOS: O hiperinsulinismo teve RR = 4,66 e p = 0,0015. A hiperglicemia apresentou um RR = 2,47 e p = 0,0123. Na intolerância a glicose o RR = 0,63 e p = 0,096. No exame normal, o RR = 0,2225 e p = 0,030.DISCUSSÃO: As alterações metabólicas podem causar tontura e vertigem e são muito frequentes na população que apresenta distúrbios cocleovestibulares. Contudo, poucos trabalhos falam sobre a relação entre a VPPB idiopática e as alterações nos carboidratos. No presente estudo, verificou-se que tanto a hiperglicemia, quanto o hiperinsulinismo são fatores de risco para recorrência de VPPB, ao passo que o exame normal foi considerado fator protetor, todos estes estatisticamente significantes. Já a intolerância à glicose não teve significância estatística no grupo avaliado.CONCLUSÃO: O hiperinsulinismo e a hiperglicemia se comportam como fatores de risco para a recorrência de VPPB idiopática, assim como o exame normal como um fator protetor.

Aplicabilidade clínica da hemoglobina glicada na evolução do paciente com hiperglicemia hospitalar / Clinical applicability of glycated hemoglobin in the evolution of patients with hospital hyperglycemia

INTRODUÇÃO: O Diabetes Mellitus (DM) consiste em uma doença crônica ocasionada pela hiperglicemia. Sabe-se que essa patologia esta presente em aproximadamente 10% das internações hospitalares, e que uma porcentagem significativa dos pacientes com Diabetes Mellitus apresenta-se sem diagnóstico prévio no momento da internação. A hiperglicemia pode provocar efeitos deletérios no organismo como processo inflamatório. OBJETIVO: Avaliar a HbA1c como ferramenta diagnóstica e preditiva da evolução clínica de pacientes com e sem diagnóstico de Diabetes Mellitus, avaliada durante período de internação hospitalar e sua relação com as complicações hospitalares. MÉTODOS: Foram avaliados 100 pacientes no período de um ano e verificado através do protocolo Institucional NUMAD (Núcleo de assistência ao Paciente Diabético) os valores de hemoglobina glicada HbA1c em pacientes com hiperglicemia. RESULTADOS: Os pacientes sem diagnóstico prévio de Diabetes Mellitus apresentaram HbA1c entre 5,8% e 7,5%, com a mediana do tempo de internação de 9 dias, sem complicações. Os pacientes com Diabetes Mellitus que evoluíram com complicações, apresentaram HbA1c entre 7,3% e 12,4% e correspondiam a 20% do estudo, com tempo de internação de 34,5 dias. DISCUSSÃO: Estudos descrevem a prevalência de hiperglicemia relacionada a mortalidade e período de internação hospitalar, e principalmente em relação a hemoglobina glicada como marcador de gravidade independente da patologia. Nosso estudo demonstrou a importância dessa ferramenta como um aliado ao tratamento hospitalar. CONCLUSÃO: A HbA1c demonstrou em nosso estudo ser um marcador prognóstico e preditivo importante em pacientes com hiperglicemia hospitalar.

INTRODUCTION: Diabetes Mellitus (DM) is a chronic disease caused by hyperglycemia. It is known that this disease is present in approximately 10% of hospital admissions, and there is a significant percentage of patients with Diabetes Mellitus presents with no previous diagnosis at admission. Hyperglycemia can cause deleterious effects in the body as an inflammatory process. OBJECTIVE: To evaluate the HbA1c as a diagnostic and predictive tool outcome of patients with and without diagnosis of Diabetes Mellitus, performed during hospital stay and its relation with the hospital complications. METHODS: A total of 100 patients in the period of a year and verified by the Institutional NUMAD protocol (service core to Diabetic Patients) the glycated hemoglobin HbA1c in patients with hyperglycemia. RESULTS: Patients with no previous diagnosis of Diabetes Mellitus had HbA1c between 5.8% and 7.5%, with the median length of stay of nine days without complications. Patients with Diabetes Mellitus who developed complications, had HbA1c between 7.3% and 12.4% and accounted for 20% of the study, with hospital stay of 34.5 days. DISCUSSION: Studies describe the prevalence of hyperglycemia related mortality and hospital stay, and especially in relation to glycated hemoglobin as a marker of severity regardless of pathology. Our study demonstrated the importance of this tool as an ally to the hospital treatment. CONCLUSION: HbA1c demonstrated in our study to be a prognostic and predictive marker important in patients with hospital hyperglycemia.

Hiperglucemia en la urgencia pediatrica. No todo es diabetes / Hyperglycemia in the pediatric emergency. Not everything is diabetes

La hiperglucemia es un hallazgo poco frecuente en la urgencia pediátrica. La hiperglucemia, glucemia ≥ 126 mg/dl, puede corresponder a un cuadro de diabetes mellitus tipo 1; el hallazgo de una hiperglucemia casual en un paciente obeso y con diabetes tipo 2; la hiperglucemia sin descompensación de una diabetes monogénica o ser una hiperglucemia por estrés. Estas últimas suelen ser no cetósicas, limitadas a la enfermedad aguda y, generalmente, no desarrollan diabetes en el seguimiento posterior. En un análisis, hayamos solo un 2,9% de casos (8/270 niños) con hiperglucemia por estrés que desarrollaron diabetes mellitus en el seguimiento posterior. El uso de insulina en los casos más graves mejora la evolución y disminuye la morbimortalidad. Existe una superposición de cuadros intermedios en la presentación de la hiperglucemia, que requiere el auxilio del especialista para desentrañar el cuadro subyacente en el seguimiento posterior.

Hyperglycemia is a rare finding in pediatric emergency. Hyperglycemia as pediatric emergency presentation (blood glucose ≥ 126 mg/dl), may correspond to a diabetes mellitus type 1, the finding of a casual hyperglycemia in an obese patient and type 2 diabetes, hyperglycemia without decompensation of the monogenic diabetes or stress hyperglycemia. The latter are often not ketosis, limited to acute illness and usually do not develop diabetes at follow-up. We found only 2.9% of patients (8/270 children) with stress hyperglycemia who developed diabetes mellitus at follow-up. The use of insulin in the most severe cases improves the evolution and decreases morbidity. There is an overlap of intermediate states in the presentation of hyperglycemia requiring specialist help to unravel the underlying state in the follow-up.

Postpartum glucose tolerance status 6 to 12 weeks after gestational diabetes mellitus: a Brazilian cohort / Reavaliação do estado glicêmico 6 a 12 semanas após o diabetes melito gestacional: uma coorte brasileira

Objectives: The aims of this study were to estimate the local rate of postpartum diabetes screening after gestational diabetes mellitus (GDM) pregnancies, and to identify clinical variables associated with retesting rates and with the persistence of decreased glucose tolerance. Subjects and methods: Prospective cohort of GDM women with prenatal delivery at a specialized center, from November 2009 to May 2012. All women were advised to schedule a 6 weeks postpartum 75-g oral glucose tolerance test (OGTT). Results: Of the 209 women included, 108 (51.7%) returned to be tested with fasting plasma glucose (n = 14), OGTT (n = 93) or random glucose (n = 1). Return was associated with lower parity rate (2 vs. 3, p < 0.001) and higher pregnancy 2-h OGTT (165 vs. 155 mg/dL, p = 0.034), but not with socio-demographic characteristics. Four women (3.7%) had diabetes, 22 (20.4%) had impaired fasting glucose or impaired glucose tolerance. Persistent hyperglycemia was associated with a positive family history of diabetes (relative risk - RR 2.41, p = 0.050), diagnostic 2-h OGTT in pregnancy (RR 1.01, p = 0.045), insulin use during pregnancy (RR 2.37, p = 0.014), and cesarean section (RR 2.61, p = 0.015). Conclusions: Even though postpartum abnormalities were frequent in GDM, rates of postpartum diabetes screening were undesirably low. As no specific clinical profile defines who will adhere to postpartum testing, it is essential to encourage all women to reevaluate their glucose status, particularly those with a family history of diabetes and more severe hyperglycemia.

Objetivos: Os objetivos foram estimar a taxa de reavaliação de diabetes pós-parto em mulheres com diabetes melito gestacional (DMG) e identificar fatores associados ao retorno e à persistência das alterações glicêmicas. Sujeitos e métodos: Coorte prospectiva de mulheres com DMG atendidas em ambulatório de pré-natal especializado, de novembro de 2009 a maio de 2012. Todas foram orientadas a agendar o teste oral de tolerância à glicose (TOTG) a partir da sexta semana pós-parto. Resultados: Das 209 mulheres arroladas na gestação, 108 (51,7%) foram avaliadas após o parto: 14 com glicemia de jejum, 93 com o TOTG e uma com glicemia ao acaso. O retorno para reavaliação foi associado com menor paridade (2 vs. 3, p < 0,001) e com glicemia de 2-h mais elevada no TOTG diagnóstico (165 vs. 155 mg/dL, p = 0,034). Diabetes foi diagnosticado em quatro mulheres (3,7%) e pré-diabetes em 22 (20,4%). Análise multivariada evidenciou que a história familiar de diabetes (risco relativo – RR 2,41, p = 0,050), a glicemia de 2 horas no TOTG da gestação (RR 1,01, p = 0,045), o uso de insulina na gestação (RR 2,37, p = 0,014) e a taxa de cesariana (RR 2,61, p = 0,015) foram os fatores associados à persistência da hiperglicemia. Conclusões: O retorno para reavaliação foi baixo, embora as alterações glicêmicas tenham sido frequentes. Como não houve fatores que indiquem quais mulheres retornarão, estratégias para aumentar a adesão são necessárias, especialmente quando há história familiar ou o DMG foi mais grave.

Diabetes subdiagnosticado e necrose miocárdica: preditores de hiperglicemia no infarto do miocárdio / Unrecognized diabetes and myocardial necrosis: predictors of hyperglycemia in myocardial infarction

FUNDAMENTO: Hiperglicemia na fase aguda do infarto do miocárdio é importante fator prognóstico. Entretanto, sua fisiopatologia não está completamente elucidada. OBJETIVO: Analisar simultaneamente correlação entre hiperglicemia e marcadores bioquímicos relacionados ao estresse,metabolismo glicídico e lipídico, coagulação, inflamação e necrose miocárdica. MÉTODOS: Oitenta pacientes com infarto agudo do miocárdio foram incluídos prospectivamente. Os parâmetros analisados foram: glicose, hormônios do estresse (cortisol e norepinefrina), fatores do metabolismo glicídico [hemoglobina glicada (HbA1c), insulina], lipoproteínas (colesterol total, LDL, HDL, LDL eletronegativa minimamente modificada e adiponectina), glicerídeos (triglicérides, VLDL e ácido graxo), fatores da coagulação (fator VII, fibrinogênio,inibidor do ativador do plasminogênio-1), inflamação (proteína C reativa ultrassensível) e necrose miocárdica (CK-MB e troponina). Variáveis contínuas foram convertidas em graus de pertinência por intermédio de lógica fuzzy. RESULTADOS: Houve correlação significativa entre hiperglicemia e metabolismo glicídico (p < 0,001), lipoproteínas (p = 0,03) e fatores de necrose (p = 0,03). Na análise multivariada, somente metabolismo glicídico (OR = 4,3; IC = 2,1-68,9 e p < 0,001) e necrose miocárdica (OR = 22,5; IC = 2-253 e p = 0,012) mantiveram correlação independente e significativa.Para análise da influência da história de diabetes mellitus , modelo de regressão, incluindo somente pacientes sem diabetes mellitus foi desenvolvido, e os resultados não alteraram. Finalmente, no modelo ajustado para idade, sexo e variáveis clínicas(história de diabetes mellitus, hipertensão arterial e dislipidemia), três variáveis mantiveram associação significativa e independente com hiperglicemia: metabolismo glicídico (OR = 24,1; IC = 4,8-122,1 e p < 0,001) necrose miocárdica (OR = 21,9; IC = 1,3-360,9 e p = 0,03) e história de DM (OR = 27, IC = 3,7-195,7 e p = 0,001). CONCLUSÃO: Marcadores do metabolismo glicídico e necrose miocárdica foram os melhores preditores de hiperglicemia em pacientes com infarto agudo do miocárdio.

BACKGROUND: Hyperglycemia in the acute phase of myocardial infarction is an important prognostic factor. However, its pathophysiology is not fully understood. OBJECTIVE: To analyze simultaneously the correlation between hyperglycemia and biochemical markers related to stress, glucose and lipid metabolism, coagulation, inflammation, and myocardial necrosis. METHODS Eighty patients with acute myocardial infarction were prospectively included. The following parameters were analyzed: blood glucose; stress hormones (cortisol and norepinephrine); glucose metabolism factors [glycated hemoglobin (HbA1c); insulin]; lipoproteins (total cholesterol, LDL, HDL, minimally modified electronegative LDL, and adiponectin); glycerides (triglycerides, VLDL and fatty acids); coagulation factors (factor VII, fibrinogen, plasminogen activator inhibitor-1); inflammation (high-sensitivity C reactive protein); and myocardial necrosis (CK-MB and troponin). Continuous variables were converted into degrees of relevance using fuzzy logic. RESULTS: Significant correlation was observed between hyperglycemia and glucose metabolism (p < 0.001), lipoproteins (p = 0.03), and necrosis factors (p = 0.03). In the multivariate analysis, only glucose metabolism (OR = 4.3; CI = 2.1-68.9; and p < 0.001) and myocardial necrosis (OR = 22.5; CI = 2-253; and p = 0.012) showed independent and significant correlation. For the analysis of the influence of history of diabetes mellitus, a regression model including only patients without diabetes mellitus was developed, and the results did not change. Finally, in the model adjusted for age, gender, and clinical variables (history of diabetes mellitus, hypertension and dyslipidemia), three variables maintained a significant and independent association with hyperglycemia: glucose metabolism (OR = 24.1; CI = 4.8-122.1; and p < 0.001), myocardial necrosis (OR = 21.9; CI = 1.3-360.9; and p = 0.03), and history of DM (OR = 27; CI = 3.7-195.7; and p = 0.001). CONCLUSION: Glucose metabolism and myocardial necrosis markers were the best predictors of hyperglycemia in patients with acute myocardial infarction.

Valor prognóstico da hiperglicemia de estresse na evolução intra-hospitalar na coronariopatia aguda / Prognostic value of stress hyperglycemia for in-hospital outcome in acute coronary artery disease

FUNDAMENTO: Na síndrome coronariana aguda (SCA), a hiperglicemia, à admissão hospitalar, está associada à presença de eventos adversos cardiovasculares em pacientes com ou sem diabetes. OBJETIVO: Avaliar o valor prognóstico da hiperglicemia de estresse na evolução intra-hospitalar de pacientes admitidos por SCA. MÉTODOS: Foram incluídos 152 pacientes admitidos, entre setembro de 2005 e fevereiro de 2010, em unidade de dor torácica de hospital terciário com diagnóstico de SCA, que apresentavam valor da glicemia laboratorial na admissão. O grupo I foi formado pelos pacientes com hiperglicemia de estresse, definida por glicemia na admissão > 126 mg/dL em não diabéticos e > 200 mg/dL nos diabéticos, e o grupo II pelos pacientes com níveis glicêmicos inferiores aos níveis estabelecidos. Analisou-se a associação da hiperglicemia e evolução intra-hospitalar. RESULTADOS: A hiperglicemia de estresse associou-se a complicações intra-hospitalares, aumento da idade e gênero feminino. Na análise multivariada, apenas gênero feminino (OR = 2,04; IC95% 1,03 - 4,06, p = 0,007) e complicações intra-hospitalares (OR = 3,65; IC95% 1,62 - 8,19, p = 0,002) se associaram de forma independente à hiperglicemia na admissão. CONCLUSÃO: A hiperglicemia de estresse é fator preditivo independente para complicações intra-hospitalares após SCA em pacientes diabéticos ou não. Os resultados alertam para a necessidade de avaliarmos a glicemia na admissão em todos os pacientes admitidos por SCA, incluindo os não diabéticos, com o intuito de identificarmos os indivíduos com maior risco de complicações.

BACKGROUND: In acute coronary syndrome (ACS), admission hyperglycemia is associated with adverse cardiovascular events in diabetic and nondiabetic patients. OBJECTIVE: To assess the prognostic value of stress hyperglycemia for the in-hospital outcome of patients admitted due to ACS. METHODS: This study included 152 patients admitted to the chest pain unit of a tertiary hospital diagnosed with ACS, who had admission blood glucose data, from September 2005 to February 2010. Group I comprised patients with stress hyperglycemia, defined as admission blood glucose concentration > 126 mg/dL for nondiabetic individuals and admission blood glucose concentration > 200 mg/dL for diabetic individuals. Group II was formed by patients with admission blood glucose concentration lower than those established. The association of hyperglycemia and in-hospital outcome was assessed. RESULTS: Stress hyperglycemia associated with in-hospital complications, age increase and female sex. On multivariate analysis, only female sex (OR = 2.04; 95% CI: 1.03 - 4.06; p = 0.007) and in-hospital complications (OR = 3.65; 95% CI: 1.62 - 8.19; p = 0.002) associated independently with admission hyperglycemia. CONCLUSIONS: Stress hyperglycemia is an independent predictive factor for in-hospital complications after ACS in diabetic and nondiabetic patients. The results highlight the need to assess admission blood glucose concentration in all patients admitted due to ACS, including nondiabetic ones, aiming at identifying those at higher risk for complications.

La glucemia de ayuno como indicador pronóstico durante las complicaciones macrovasculares agudas / Fasting glycemia as a prognostic indicator during the acute macrovascular complications

Introducción: Con la intención de evaluar la influencia de la hiperglucemia en la evolución de pacientes con accidentes macrovasculares agudos se estudiaron 73 personas hospitalizadas con síndrome coronario agudo o accidente cerebrovascular, independientemente de su condición de padecer diabetes mellitus (21,9 por ciento) o no. Métodos: Se registraron complicaciones tempranas (vasculares, sépticas y muerte) y se determinó la glucemia al ingreso, de ayuno y posprandial, así como la hemoglobina glucosilada (HbA1c). Se calcularon las medias de cada determinación y se compararon los grupos de pacientes complicados con aquellos que evolucionaron satisfactoriamente. Resultados: Se halló que solo la glucemia de ayuno se asoció con un peor pronóstico (p=0,004), lo que no se confirmó con el resto del perfil glucémico ni con la HbA1c (p=0,25), aún cuando todos los promedios fueron superiores en el grupo de pacientes complicados. El perfil lipídico tampoco se asoció con las complicaciones posteriores a un proceso macrovascular. Conclusiones: La hiperglucemia de ayuno, en rango diabético, se asoció con una evolución desfavorable en el grupo de pacientes estudiados

Introduction: To assess the influence of hyperglycemia on the course of patients with acute macrovascular accidents, 73 patients admitted due to acute coronary syndrome or cerebrovascular accident were studied, independently of its diabetes mellitus (21,9 percent) or not. Methods: There were early complications (vascular, septic and death); authors determined the presence of glycemia at admission, fasting and postprandial, as well as the glycosylated hemoglobin (HbA1c). The means of each determination were estimated and the groups of patients complicated were compared with a satisfactory evolution. Results: There was found that fasting glycemia was associated with the worse prognosis (p = 0,004) even though all averages were higher in the complicated patients group. The lipid profile was not associated with complications after a macrovascular process. Conclusions: Fasting hypoglycemia, in diabetes rank was associated with a unfavourable course in the group of study patients

Dexametasona para profilaxis de náuseas y vómitos postoperatorios: efecto sobre la glicemia en pacientes con diabetes mellitus tipo 2 y en no diabéticos sometidos a cirugía laparoscópica / Effects on blood glucose of prophylactic dexamethasone for postoperative nausea and vomiting in diabetics and non-diabetics

Background: Postoperative nausea and vomiting (PONV) prophylaxis with dexamethasone may produce significant hyperglycemia in the postoperative period. Aim: To evaluate if this effect is of greater severity in type 2 diabetics compared with non-diabetic patients. Material and Methods: Forty non-diabetic and thirty type 2 diabetic patients undergoing laparoscopic cholecystectomy were studied in a prospective and double-blind fashion manner. Patients were randomly distributed into 4 groups: Group I, non-diabetics control (n = 20), Group II, non-diabetics dexamethasone (n = 20), Group III, type 2 diabetics control (n = 15), and Group I V, type 2 diabetics dexamethasone (n = 15). Immediately after induction, patients in groups I and III received isotonic saline and patients in the dexamethasone groups received 8 mg iv of the steroid. Capillary blood glucose concentrations were measured at baseline and every 2 hours during the first 12 hours since the start of surgery. A linear mixed effect model, adjusted for baseline capillary glucose concentration, age and duration of surgery was used to analyze the data. Results: No effect of the presence of diabetes mellitus was observed in the evolution of glucose concentrations. There was a difference in capillary glucose concentrations between patients who received dexamethasone and placebo that started 2 hours post-intervention, reaching a mean maximum difference of 34 mg/dl (adjusted model, p < 0.001) at 10 hours post-intervention. Conclusions: In this study, Type 2 diabetic patients did not show a higher susceptibility than non-diabetics to develop postoperative hyperglycemia after the use of prophylactic dexamethasone for PONV.

Impact of screening and monitoring of capillary blood glucose in the detection of hyperglycemia and hypoglycemia in non-critical inpatients / Impacto do rastreamento e monitoramento de glicemia capilar na detecção de hiperglicemia e hipoglicemia em pacientes não graves internados

Objective: To evaluate the impact of screening hyper and hypoglycemia measured by capillary glycemia and standard monitorization of hyperglycemic patients hospitalized in regular care units of Hospital Israelita Albert Einstein. Methods: The capillary glycemia was measured by the Precision PCx (Abbott) glucosimeter, using the PrecisionWeb (Abbott) software. The detection of hyper and hypoglycemia during the months of May/June were compared to those of March/April in 2009 and to the frequency of the diagnosis of diabetes in 2007. Results: There was an increase in the glycemia screening from 27.7 to 77.5% of hospitalized patients (p < 0.001), of hyperglycemia detection (from 9.3 to 12.2%; p < 0.001) and of hypoglycemia (from 1.5 to 3.3%; p < 0.001) during the months of May/June 2009. According to this action 14 patients for each additional case of hyperglycemia and 26 cases for each case of hypoglycemia were identified. The detection of hyperglycemia was significantly higher (p < 0.001) than the frequency of registered diagnosis related do diabetes in the year of 2007. Conclusions: the adoption of an institutional program of glycemia monitorization improves the detection of hyper and hypoglycemia and glycemia control in hospitalized patients in regular care units.

Objetivo: Analisar o impacto do rastreamento de hiper e hipoglicemia mensurada por glicemia capilar e da monitorização padronizada em pacientes hiperglicêmicos internados em unidades não graves do Hospital Israelita Albert Einstein. Métodos: A glicemia capilar foi mensurada com glucosímetro Precision PCx (Abbott), rastreada com software PrecisionWeb (Abbott). A detecção de hiper e hipoglicemia no bimestre Maio/Junho foi comparada ao bimestre Março/Abril de 2009 e ainda quanto à frequência de diagnósticos relacionados ao diabetes no ano de 2007. Resultados: Houve um aumento do rastreamento de glicemia de 27,7 para 77,5% dos pacientes internados (p < 0,001), na detecção de hiperglicemia (de 9,3 para 12,2%; p < 0,001) e de hipoglicemia (de 1,5 para 3,3%; p < 0,001) no bimestre Maio-Junho de 2009. Com essa iniciativa, foram rastreados 14 pacientes para cada caso adicional de hiperglicemia e 26 pacientes para cada caso de hipoglicemia. A detecção de hiperglicemia foi significantemente maior (p < 0,001) que a frequência de registros de diagnósticos relacionados ao diabetes no ano de 2007. Conclusões: a adoção de um programa institucional de monitoramento de glicemia melhora a detecção de hiper e hipoglicemia e o controle de glicemia em pacientes internados em unidades não graves.

Training of non-physician practitioners to identify and refer diabetic patients

To improve the practices of non-physician practitioners on early diagnosis and referral of patients with diabetes mellitus. Study will be conducted in a peri-urban village community in Lahore, Pakistan, during 2007 - 2008. Quasi - experimental study, one group before and after design was used to document the effect of training of non-physician practitioners on improving their diabetic patient identification practices and referral to the hospital for diagnostic and treatment facilities. Fasting blood glucose test was used to identify hyperglycaemics out of those referred by the NPPs. Patient referral was increased by 48.44% after training. Identification of hyperglycaemic patients on the basis of signs and symptoms was 47% before and 48% after training and the difference between two proportions was not significant. increased number of referral showed motivation of NPPs towards the task however more prolonged and structured training program is required to utilize their services in community as part of our health care delivery system
